摘要
目的 探讨磁共振成像 (MRI)在产科的应用价值 ;研究胎儿的生长发育状况及妊娠并发症。方法 采用超导 0 35T磁共振成像仪 ,对 44例中、晚期孕妇进行磁共振成像 ,观察胎儿各脏器及母体附属结构的形态、信号变化。结果 胎儿的大多数脏器及母体的附属结构 (如胎脑、胎心、胎肺、胎肝、胎盘、子宫等 )被良好的显示 ,其显示率为 6 8%~ 10 0 % (胎儿肠腔及肾脏等显示率较低 )。胎脑、胎肝等部分脏器的细微结构及其发育成熟度也能被良好揭示。 2例前置胎盘、12例脐带绕颈及 1例胎儿宫内发育迟缓等异常被发现。结论 MRI能较好地揭示胎儿各个脏器的生长发育状况 。
Objective To discuss the application of magnetic resonance imaging (MRI)in obstetrics,and to study the growth and development of fetus and complications in pregnancy.Methods 44 pregnant women (middle or later gestational ages) were imaged with MRI at 0 35 T(tesla).Results The morphological structures and signal changes of fetal organs and maternal auxiliary structures including fetal brain,heart,liver,placenta,and uterus were clearly shown,the demonstration rate being 68%~100%(demonstration rate of fetal intestine and kidney was relatively lower).Microstructures and developmental maturity of some organs such as fetal brain and liver were also demonstrated.Two cases of placenta previa,12 cases of umbilicalis winding cervix,one case of intrautrine growth retardation and some other abnormalities were disclosed.Conclusion MRI is useful in demonstrating the growth of fetal organs,and revealing pregnancy complications and developmental abnormalities of the fetus.
